IM PROVEMENT IN WRENCHES.

- Specification forming part of Letters Patent No. 191,459, datedNovember 27, 1877; application filed October 3, 1877.

To all whom it may concern: Be it known that I, CHARLES A. OORMAN of YGochituate, in the county of Middlesex and State of Massachusetts, haveinvented certain new and useful Improvements in Wrenches; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled. in the I art towhich it pertains to make and use it, reference being had to theaccompanying drawings, which form part of this specification.

My invention relates to an improvement in wrenches; and it consists incombining with the wrench a vise, in such a manner that one end of thejaws can be used for unscrewing nuts and bolts, and the other end as avise, in which all kinds of small articles can be held with as much easeand a great deal more freedom, so far as-turning the articles in allsorts of positions is concerned, as can be done in an ordinary vise, allof which will be more fully described hereinafter.

The accompanying drawings represent my invention.

a represents the handle, I) the shank, and c Q the two jaws, the outerjaw being secured to the head of the shank, and the inner jaw slidingback and forth over the shank, in the usual manner. The longer ends atof the jaws are shaped in the usual manner, and form the ordinary wrenchfor unscrewing nuts and bolts of all kinds. The opposite or shorter ends0 of the jaws are shaped like the jaws of a commonvise; and as they fitaccurately and snugly together, and have the enlarged opening 0 throughtheir sides in the same manner as a vise, it is evident that the wrenchcan not only be used as a wrench, but also as a vise for all smallarticles.

held in position so as to move evenly and smoothly back and forth uponthe shank.

The nut l is passed over the screw, and is held by a notch cut in theside of the shank, in the usual manner.

A wrench having a vise combined with it, as here shown and described,gives a much larger range of usefulness to the vise, and serves for somany different purposes that a vise will not be required except forlarge articles.

I am aware that wrenches have been made having jaws that project eachside of the shank, and this I disclaim.

Having thus described my invention, 1 claim- In a wrench, thecombination of handle a, shank b jaws 0, having the groove 0 acrosstheir inner sides, slide 9, screw h, nut l, and brace c, all the partsbeing constructed and arranged to operate substantially as shown.

In testimony that I claim the foregoing I have hereunto set my hand andseal this 27th day of September, 1877.
